CLOSING DEVICE FOR VESSELS CONTAINING VOLATILE LIQUIDS.V

SPECIFICATION forming part of' Letters Patent N o. 628,460, dated July 11, 1899. Appiipahof nea Apriti, 1899y Serin No. 711,656. (No mana in Closing Devices for Vessels Containing Volatile Liquids, of which the following is a specification.

This invention relates to devices for closing vessels containing ethyl chlorid and other :o highly-velatiie liquids, and is more particulai-ly adapted to vessels formed with a capillary o1 1tfiow-aperture to allow of directly prod ucinga ii ne jet. Smaller-sized vessels of this kind (which are made ehieiiy of glass) have i5 hitherto been eiosed by means of a metal mount, which is cemented over vthe capillary.

outiiow portion or tube, and eira metal cap which is adapted to be screwed or otherwise fastened on the said mount. Now this mode of zo closure is complicated and troublesome, but is also open te otherobjeetions. As the length ofA the mount is fixed and the capillary tube must necessarily be broken off at the end of the mount man" vessels have had to be subse- 2 5 qucntly thrown away because the crosssec tional area of the capillary aperture at 'this place was not of the propersize, Ithasgherefore become necessary to make the vessels intended for this kind of closinglilevice accordgo ing to a complicated process, in which the capillary tube is not produced by simply drawing out in a heating-flame in the usual iway, but in which a capillary tube of uniform diameter melted onto the vessel. It has also been common to form bottles with large mouths or discharge-openings with an external receding shoulder between the mouth and neck and to construct a c ap having an inter' nal rubber washer and having elastic claws. 4o bent inwardly to snap behind this shoulder when the cap is applied to the neck, so that the elasticityfof the claws causing them to wedge behind the shoulder will draw the cap downwardly, and thus cempressthe packing Such cen'- struetions have required much accuracy in order to insure a perfectclosure and have ne eessitatedf'ehe use of considerable force to appiy or remove the cap. ly the present inated and the necessity for the expensive and complicated method of forming the vessels just referred to is done away with. The vessels may be drawn out to a capillary jet in the ordinary way, and the closure is independent of the metal mount before described.

My invention will be understood from the annexed drawings, which represent a vessel vention these drawbacks are entirely obviof the kind in question fitted with my immetal caf) or s f pper a, the cylindrical lower portionlof which is slotted or slit in such a manner as to form elastic limbs or extensions b b". The cap a, is provided inside its upper end with a small washer c, of caoutchouc or A other suitable materiah'whieh effects the tight closure of the capillary outow-aperture (l of the vessel e. .This cap is held in position by means of the grip of the elastic limbs or extensions b o upon the glass capillary tube,

and thus the usual'metal mount previously used is dispensed with and the drawbacks connected therewith are obyiated.

l The 'lmproved bottle is preferably constructec with a reduced tip t, a swell or tapering shoulder j inwar ly thereof, an elongated smooth cylindrical eek vk beginning at said swell j audn'eeting the body-shoulder Z on-the bottle c. y, Ehe neck k is of considerable thickness to aiiiord strengthvand is preferably of uniffprm diameter. The neek-shoulder 7' is smoth and tapering and serves as a wedge for separating the limbs of the cap. The tip is of r atively small diameter, so a's to afford at its d a limited area of surface to be pressed against the washer c, and also it is preferablyof less diameter than the minimum distance between the limbs of the cap when the latter is removed, so that this tip easily passes between the limbs for guiding the cap during its application to the bottle, so that the swell j vcan gradually'jsebarate the-'limbs after the cap haspartlyenveloped the tip.-
